I am trying to calculate a point on one side of a road using a pin found on the other side for direction. I used the % offset command in the form of 1..2%+20.117 expecting a point to be created so that the road would be 20.117m wide..... It didn't work!
Is there a bug reported for this command?

I see the problem. I was trying to use the offset from the second point to calculate a line. The command is used to calculate a point offset a line, not a line perpendicularly distant from a point - a different problem.
Having said all that is there a way to get the result I am looking for?
I have a pin on the east side of a road (Pt 1) and another pin some distance up the road to the north on the west side (Pt 2). I want to calculate the lot corners on the east side of the road north from Pt 1 using a perpendicular offset of 20m to Pt 2 as direction. I could draw a circle of 20m radius around Pt 2 and draw a line from Pt 1 to a tangent point on the circle but that is cheating. Is there a COGO command for this case?

Just so I get this right, you want to create a new point on the East side of the road that 20 m from pt 2 and the azimuth from point #1 to the new point is unknown. The point we want to create must be along a line that is 20 m (Perp) from point #2 to the new line.

There are no other constraints in this problem like a distance or azimuth? Please let me know.
